Description

Is characterization for HDMI equalization available for Zynq UltraScale+ yet? What is the recommendation for HDMI equalization with Zynq UltraScale+?

Solution

For 7 Series GTX and UltraScale GTH devices, the current recommendation does not include external TMDS equalization or repeater chips.

The recommendation for those architectures is to use passive TMDS emulation circuitry as recommended in TB-FMCH-HDMI4K.

While we expect similar performance with Zynq UltraScale+ MPSoC GTH, characterization is pending. Until further notice, the recommendation is to use an external TMDS equalizer or repeater chips on the receiver interface.

Examples of external TMDS equalizers are (but are not limited to) TMDS181 from Texas Instruments and PS8409 from Parade Technologies.
